| Abstract | ||||
| The experiments were carried out to develop and construct a local shelling machine for shelling peanuts. The main parts of the peanut shelling machine were as follows: feed hopper, shelling chamber, shelling drum, concave sieve, blower, and electrical motor with transmission pulleys and V-belts. The performance of the developed machine was studied under the following parameters: three different drum speeds of (300, 400, and 500 rpm) corresponding to (3.45, 4.6 and 5.75 m/s); three different peanut moisture contents of (8.96, 12 and 15.61%); and three different feeding rates of (60, 90 and 120 kg/h). The performance of the manufactured shelling machine was evaluated, taking into consideration the following indicators: machine productivity, breakage percentage, shelling efficiency, cleaning efficiency, consumed energy and operational cost. The experimental results reveal that the highest value of machine productivity was 50.28 kg/h while the lowest values of both consumed energy and operational cost were 9.98 kW.h/Mg and 343 L.E/Mg were obtained at drum speed of 400 rpm (4.6 m/s), moisture content of 8.96% and feeding rate of 120 kg/h. The highest value of cleaning efficiency was 98.8%, while the lowest value of breakage percentage was 2%. These values were obtained at a drum speed of 300 rpm (3.45 m/s), moisture content of 15.61%, feed rate of 60 kg/h; and constant air speed of 10.6 m/s. The shelling efficiency was 100 % under all machine test runs. | ||||
